I love both companies for different reasons. I like Intamin's adventurousness when it comes to doing new things. The industry needs it because as the years go by, it's becoming more difficult to think of new concepts and also go on to turn them into working attractions. Unfortunately, that can lead to, as you said yourself, "technical headaches". But when their rides are working, they're
mostly great.
Then we have B&M. Although I love their older work like Nemesis, Oblivion, Kumba and Montu, B&M's more modern creations are mostly too soft and I also dislike their repetitive layouts that many American B&M's have where the ride just strings a load of the same inversions together. I went on Hulk five times in one day a few weeks ago and found the start to be great, but from the mid-course brake run and onward, it's a bit dull. It looks like that has more or less become the norm for their coasters. Just look at the plans for Cedar Point's Gatekeeper, or Port Aventura's Shambhala.
However, I think it's great that B&M still perfect their ideas. The one coaster that B&M can probably still nail is the mega and hyper coaster, as the smoothness is perfect for creating the air-time hills, and speed and height will probably be enough to let them off for not being as intense.
I wouldn't say that modern B&M's are boring, they just aren't generally as thrilling as most of their 90's creations. Intamin are thrilling, but at what cost? If only the two could work together to make ride that has the intensity and uniqueness of an Intamin concept, but have the refinement and grandeur of a colossal B&M.
That said, B&M could just go back to what they used to do but be more open to doing new things. Although that's probably easier written than done.
Their wing rider is a fantastic improvement over the Intamin and S&S variants, but I rode the Swarm and wasn't left yearning for more. It was impressive to look at (for a UK coaster) and the ride offers a unique experience, but apart from the first drop under the plane wing, it was average at best. Of course, that's my personal opinion, and I know that some people thought that it was better than Nemesis when it first opened, but I just can't see that at all. Nemesis is more or less relentless once it gets going whereas the Swarm has the look and theme that says "
I'm an adrenaline machine! COME AT ME!", whereas the ride experience is far from that. It was never supposed to be as intense or insane Saw or Stealth, but it didn't come close to what I was expecting. I wanted Air on steroids but it felt like I got a taller version of Air with a different theme (albeit with a similar amount of theming to it).
Perhaps it was wrong of me to have expectations like that? Perhaps not? Either way, what I got wasn't what I thought I was seeing whilst waiting in the cattle-pen below, and I know that I'm not the only one that feels the same about it.
Whilst B&M made my favourite coaster, they aren't my overall favourite ride manufacturer. Intamin aren't either, although I've yet to ride Intimidator 305.
Sorry for picking on B&M so much, I just find it frustrating that they can't go back to what they used to do. After all, if it ain't broke, don't fix it!
